Please help advice needed

hello this is the first time I've ever done anything like this I have got two daughters and I'm trying for my 3rd baby buts its proving to be a lot harder this time been trying now for bout 6months my period is very regular every 28 days but this month was 2 days late and its barely lasted 2 days and the blood is more pink than any other time could this be implantation bleeding or is more wishful thinking xxx
